embodiment 10

Preferred Embodiment 10

The fire retardant wooden door 10 of the preferred embodiment of the present invention is represented in detail by FIGS. 1 through 6 of the patent drawings. The fire retardant door 10 is used to fireproof an area and to prevent fire from spreading to other areas within a home dwelling, commercial building or industrial plant.

As shown in FIG. 1, the fire retardant wooden door 10 includes stiles 12 and 14, rails 16 and 18 and is hingedly connected within a door frame 20. The door frame 20 includes a left side doorjamb 22, a right side doorjamb 24, an upper header 26 and a lower sill 28. Suitable hinges 30 are used to mount the door 10 to the hinge jamb 22 in a manner which allows the door 10 to be opened or closed. A handle 32 is provided to operate a latch 34 which retains the door in the closed position.

The fire retardant wooden door 10 further includes a center panel 40, an upper panel 50 and a lower panel 60. Panel 50 has edges 52, 54, 56 and 58, and panel 6...

embodiment 200

Alternate Embodiment 200

The fire retardant wooden door 200 and its component parts of the alternate embodiment of the present invention is represented in detail by FIGS. 7 and 8 of the patent drawings. The fire retardant door 200 is also used to fire proof an area and to prevent fire from spreading to other areas within a home dwelling, commercial building or industrial plant. All aspects of the second embodiment of the fire retardant wood door 200 are exactly the same except for the use of fire-tempered glass panels 250 and 260 within an alternate door frame 220 which replace the wood panels 50 and 60 of the fire retardant wooden door 10 of the preferred embodiment.

In all other aspects, all of the component parts are exactly the same as the preferred embodiment of the fire retardant wood door 10 except for using of the fire tempered glass panels 250 and 260 within the door frame 220, as shown in FIGS. 7 and 8.

Abstract

A fire retardant wooden door that prevents the spread of fire through the door during a fire. The fire retardant wooden door has at least one door panel connected to stiles and rails by tongue and groove joints, and the tongue and groove joints have intumescent material therein. Each of the tongue and groove joints includes a tongue section having the intumescent material along a distal edge of the tongue section which expands upon exposure to heat or fire to seal the tongue and groove joints in order to prevent the heat or fire from passing through the door during a fire. Each of the tongue sections includes an interior channel extending along the axis of the tongue section, and the interior channel extends into the door panel. The interior channel has the intumescent material embedded therein which expands upon exposure to heat or fire to further seal the tongue and groove joints in order to prevent the heat or fire from passing through the door during a fire.

Description

The present invention relates to a fire retardant door, and more particularly to a fire retardant wooden door having intumescent materials therein that provides additional fire resistance for preventing the spread of fire through the fire retardant wooden door and door frame.A fire retardant door, often referred to as a "fire door," is installed in homes, commercial buildings, and industrial plants for preventing the passage or spread of fire from one part of the building to another. In the interest of public safety, standards have been set by governmental agencies; and by municipal, county and state building code authorities and insurance companies for the installation and performance of fire doors. The standards require that the fire retardant doors be installed in wall openings and that they pass industry-wide acceptance tests.Standard test methods for fire door assemblies, such as ASTM E-152, UL 10(b) or NFPA 252, measure the ability of a door assembly to remain in an opening du...
